量子猝灭后无序诱导的动力学Griffiths奇异性

Disorder-induced dynamical Griffiths singularities after certain quantum quenches

José A. Hoyos, R. F. P. Costa, J. C. Xavier

摘要:

我们证明了在一类无序量子系统中,在一定的量子猝灭后的时间窗口内,动力学配分函数不是解析函数。我们将这种行为与具有非典型不均匀性配置的罕见大区域相关。我们还量化了相关的奇异性的强度和他们的签名在实验和数值研究。

英文摘要:

We demonstrate that in a class of disordered quantum systems the dynamical partition function is not an analytical function in a time window after certain quantum quenches. We related this behavior to rare and large regions with atypical inhomogeneity configurations. We also quantify the strength of the associated singularities and their signatures in experiments and numerical studies.
